RE: Intercompany question - How do I understand Outbound Purchase Item No. Type in Navision?
Common Item No can be used for intercompany transactions.
Cross Reference Numbers can be your customer's number translated to your number, your vendors number translated, etc. You can enter your vendor item number in the Cross Ref field on the PO line and NAV will find your number. If entered, this will print on your PO
Vendor Item No. is similar to Cross Reference numbers, you can have multiple vendor's items numbers in the vendor item catalog which is used in the Planning worksheet
Internal No, is not a standard field.
